Ludorum plc announced today that its hit train-based preschool series, ‘Chuggington,’ will make its fourth season debut on Disney Junior on Sunday, October 20, 2013 at 7:00 pm ET/PT with its first-ever primetime Chuggington special, ‘Chug Patrol: Ready to Rescue!’ The newest season of the vibrantly-colorful animated series promises to deliver even more action and adventure with everyone’s favorite trainees — Wilson, Brewster and Koko — along with exciting new characters and locations.

The half-hour special follows trainee Wilson as he becomes a member of Chug Patrol — Chuggington’s rescue squad — under the watchful eye of his new mentor and Chief of Chug Patrol, Jackman, who makes his Chuggington debut. Wilson’s training has only just begun when he is put to the test — Koko is trapped in Rocky Ridge Mine and it’s up to Wilson to rescue his friend and save the day!

Just following the special’s premiere, additional high-speed episodes will roll out through the fall and into spring 2014 with new characters Hanzo and Zack — along with Jackman — and new locations for viewers to explore, including the Drop and Load Yard, the Working Wheels Service Yard and the Chug Patrol Headquarters.

Helping to mark the start of season 4 is the newly-released interactive 3D Chuggington storybook app Chug Patrol: Ready to Rescue. The debut app lets young fans relive the adventures of the upcoming TV special and join in on all the action for themselves, as they complete challenges alongside the trainees and earn Chug Patrol badges along the way. The Chug Patrol: Ready to Rescue app was produced in collaboration with award-winning digital book developer, StoryToys, based in Dublin, Ireland.

In addition, the newest Chuggington release in the preschool-favorite DVD series from Anchor Bay Entertainment, which shares the title, ‘Chug Patrol – Ready to Rescue’ features six action-packed episodes, including the super-sized special to further extend the fun all the way down the tracks.

Chuggington airs daily on Disney Junior at 7:30 am and 1:30 pm with additional airings throughout the day and evening.
